I could see this being used for home heating with an attached greenhouse. Let the sun heat up the air in a greenhouse and then pump that air through pipes embedded underneath the flooring of your house. The flooring would then radiate that heat slowly over a long period drastically reducing the need to heat the air in your house. Great idea!
Yes I thought of that as well. In fact the
rocket mass heater thing is something that fascinates me at the moment and I've started another
thread about an idea about that in the
rocket mass heater forum (otherwise it will get confusing!).
Back to this sand climate battery - anyone else think its a good idea? Does anyone know any details? Is there a better way to prevent overheating in a greenhouse and usefully store the heat?
